   ASC & EuroCC Austria & linaroforgeThis training course provides two 120
  minute sessions to enable users to maximize their usage of the Forge tool
 s. We will provide an overview of Linaro Forge\, a cross platform\, integr
 ated environment for debugging and optimizing parallel codes at any scale.
  We will provide hands-on demonstrations and exercises of how Linaro Forge
  reduces development time\, simplifies debugging\, and eases application p
 erformance enhancement on HPC systems.Agenda & Content10:00 - 12:00   Ses
 sion 1: Ensuring Program Correctness with Linaro DDTUsing sample codes\, w
 e will walk through the major capabilities of the debugger to illustrate h
 ow DDT can debug applications ranging from a single thread to large scale.
 Submitting a Forge job on your batch systemUsing semantic analysis tools t
 o catch bugs before you even run the codeHow to use sparklines to visualiz
 e variable values across processes and threadsIllustrate memory debugging 
 to trap array out of bounds errors and memory leaksUsing the array viewer 
 to visualize multi-dimensional variablesUsing watchpoints to halt executio
 n dependent upon expression valuesOffline debugging for large scale debugg
 ing\, catching non-deterministic errors and continuous integrationTrace po
 ints\, a flexible and deterministic printf alternativeModifying the defini
 tion of your program without re-building using the Evaluate WindowDebuggin
 g Nvidia GPU applicationsDebugging Python applications13:00 - 15:00   Ses
 sion 2: Performance Engineering with Linaro Performance Reports and Linaro
  MAPWe will illustrate how in a matter of minutes you can understand the n
 ature of your application’s performance. We will introduce best practice
 s to attain and maintain optimal performance.Understanding the performance
  road mapUsing Performance Reports to understand your application’s over
 all performance characteristicsCharacterize file IO behaviorIsolate worklo
 ad imbalance issues in codes at any scaleMeasure energy consumption of wor
 kloadsSee how the amount of time spent in memory operations varies over ti
 me and processesIsolate problematic memory access patternsDetermine how we

 ipants should be familiar with submitting jobs\, understand MPI applicatio
 ns\, and know at least one of the programming languages C\, C++\, Fortran\
 , or Python. In addition\, they should have a basic grasp on debugging and
  performance engineering.Target audienceCourse for academia\, industry\, a

 IVE ONLINE COURSE (using Zoom).Hands-on labsAll participants will get a te
 mporary user account on VSC-5 to do the hands-on labs.Accepted participant
 s will be contacted a few days before the course and asked to do a short P
 RE-ASSIGNMENT that has to be completed before the course starts.LecturersR
